Maytronics Dolphin Supreme M5 disposable filter bags (pack of 10) - 9991431-ASSY

Maytronics Dolphin Supreme M5 disposable filter bags (pack of 10)

These are the OEM disposable filter bags for the Dolphin Supreme M5 robotic pool cleaner, sold as a kit of ten. Each bag slots into the dedicated disposable filter frame inside the Supreme M5’s filter and cartridge holder assembly, trapping fine debris on every cleaning cycle.

What these disposable bags do in the Dolphin

Each bag acts as a single-use fine filter liner inside the Supreme M5’s filtration chamber. Instead of rinsing a reusable bag after every run, you lift out the loaded bag, discard it, and drop in a fresh one. The bags are rated for approximately three cleaning cycles apiece before disposal, so a pack of ten covers a substantial stretch of the season without any bag-washing downtime.

Which Dolphin models they fit

SKU 9991431-ASSY is listed directly in the official Maytronics Supreme M5 spare-parts diagram as the correct disposable filter kit for that model. The bags seat into the Supreme M5’s disposable filter frame (part 9980732); always verify your robot’s part diagram before ordering, as physically similar bags carry different part numbers for other Dolphin lines.

Signs they need replacing

Replace the current bag when you notice reduced suction at the intake, visible tearing or saturation of the paper material, or debris escaping back into the pool after a completed cycle. A clogged or degraded bag restricts water flow through the impeller circuit and forces the motor to work harder, so timely replacement protects the motor unit as well as filtration quality.

How to install them

Open the Supreme M5’s filter access hatch and lift out the cartridge holder. Unclip the locking hook (part 9980731), slide the spent bag off the disposable filter frame, and press a new bag firmly onto the frame until it seats flush. Re-clip the locking hook, reinsert the cartridge holder, and close the hatch. No tools required; the swap takes under two minutes.
